Not really. The rarity is based on encounter rate, so if a Pokemon has an encounter rate at 20% or above, it cannot be stated as "Rare" even if it is the rarest Pokemon on the route / place. Besides, we still have "Very Rare" for Pokemon that has an encounter rate below 5%.

However, currently we can only test things out by ourselves. It is usual for players to have different views because without the official encounter rate, players can only deduce the rarity by subjective gaming experience. So far, the only confirmed encounter rate is Riolu on Route 8 (3%), confirmed by one of the main developers.
